'WATER-CLOSET SYSTEM FOR RAILWAY-CARS.

Application filed May 6, 1915.

To all whom tm/cy concern:

Be it known that I, EARL Gr. WATROUS, a citizen of the United States,residing at Chicago, in the county of Cook and State of lllinois, haveVinvented a certain new and useful Tater-Closet System for Railway-Cars', o1"- which the following is a specification. y

My invention relates to a water closet system for railway cars and thelike and the object thereof is to provide a system in which thedischarge of a water closet is temporarily stored or retained 'in asuitable tank or reservoir which is in communication with the watercloset or closets of the car and capable of being discharged from the`tank or reservoir at any time and at any desired place and also whilethe car is in motion, such discharge being accomplished preferably bymeans of compressed air which may be supplied from a special airreservoir receiving compressed air from the air brake By means of thissystem the many disadvantages and 4inconveniences experienced in thepresent system of water closet as employed on Pullman cars and otherrailroad cars, in which system there is practically immediate discharge,are avoided, such as for instance the necessary locking of the closetrooms when the car is at terminals or at stations.

lnv the drawings Figure l is a sectional elevation illustrating oneembodiment of my invention, and showing a part of a car ioor, the closetthereon and the storage tank or reservoir communicating therewithtogether with the air pressure connections; Fig. 2 a side elevation of apart of the tank and the water closet discharge connection and theairsupply connection; Fig. 8 a sectional view, on a larger scale than inthe other views, of the valve mechanism :For controlling the compressedair to the tank or reservoir, and Fig. 4 an elevation partly in sectionofV a modified form of construction. in the drawing l have shown andwill hereinafter describe my present and preferred form of systemwithout intention of limiting myself thereto except as expresslyrequired by any speciiic claim. l

Any suitable water closet of the jet type such as the one illustrated inFig. 1 and marked 1 may be employed, the same being supported upon thefloor 2 of the car. Y The discharge ci the closet communicates withSpecification of Letters Patent.

a discharge pipe 3 which in turn communicates with the interior of thedischarge tank or reservoir 4. As herein shown the discharge pipe 3 isconnected by means of the elbow 5 with a il"litting 6 resting on top ofthe tank 4 and into which is screwed or 0therwise secured the verticaldischarge pipe 7 which in the present instance extends diametricallyinto the interior of the tank.

As shown the pipe 7 terminates near the bottom of the tank adjacent abottom drain opening closed by the screw plug 8, a cavity or small well9 being formed between the plug and the lower end of the pipe 7 Bypreference, for a purpose hereinafter eX plained when the mode ofoperation is described, the lower end of the pipe 7 is provided withrounded edges, in the present instance by means of a shell 10 of theshape shown according to which the lower edges are inturned andscrew-threaded 'to lscrew upon the lower end of such pipe, therebyforming the rounded edges 10a.

The fitting 6 is provided with a discharge opening 11 which communicateswith the higher discharge or delivery pipe 12 which is led any distanceand to any point desired for the final delivery of the discharge ofwater and soil from the tank.

Referring to the compressed air connections and the valve mechanismtherefore, such mechanism comprises a valve casing 13 having threeseparate connections, to wit, first the connection 14 communicating witha source of con'il'iressed air, second a connection 15 leading into thetop of the tank and third a connection 1G which in the present instanceis shown as communicating with the fitting 6 and of course with thedelivery pipe 12 although as will be understood such connection 16 mayrun directly to the atmosphere. The connection 14 communicates with apassage 17 in the casing which terminates in a port 18 which port isgoverned by Va valve 19. rlhis valve has a stem 20 extending upwardlythrough the top of the casing and through the car floor and provided atits upper end within the 'car with the hand wheel 21 or the like,although any other type of valve such as a slow closing valve may beemployed. The valve stemfZ() is screw-threaded intermediate its lengthat 22 so as to be screwed up or down within the casing as the hand wheelisturned in one direction or the other thereby opening or closing thevalve.

When the parts of the valve mechanism arein the position illustrated inFig. 3 the valve is seated to close the port 18 so that no air pressurecan flow through such mechanism and the top of the tank is open toatmosphere through the connection 15, interior of casing 13, connection16, tting 6 and delivery pipe 12.

` The discharge Afrom the water closet p asses through the pipe 3,iitting 6 and into pipe 7 and from thence into the tank, the same level'being maintained in the tank and pipe 7 and forcing the contents of thetank upwardly through the pipe 7, through port 11 and delivery pipe 12.The compressed air may be supplied until all or a portion of thecontents of the tank, as may be desired, are discharged whereupon thevalve 19 is operated to close port 18 and to be open at its seat 23whereupon the supply of compressed air is shut off and the tank relievedof pressure and opened to atmosphere. The purpose of the rounded orrolled-over edges 10L at the lower end of pipe 7 is to prevent thecatching of toilet paper or the like upon the edge of the pipe whichwould otherwise be the case during the discharge of the contents of thetank.

In Fig. 4 I have shown ak modied form of construction which is the sameas shown in Fig. 1 with the exception that there are added thereto twovalves Jfor controlling respectively the outlets of the discharge pipes3 and 12, these valves being in the present instance operable in unisonand also automatically as an incident to the operation of the valve. Inaccordance with this modication there is arranged within the fitting 6and at the end of the discharge of the elbow 5 which is connected to thepipe 3 a pivoted flap valve 24 which is secured to an axis or pin 25projecting through one side of the :Fitting and connected to a bellcrank 26. One arm of this bell crank is connected by means of a link 27tol a lever 28 pivoted at its outer end to a stationary bracket 29whichr is supported upon the valve casing 13. The arm 28 works betweentwo collars 30 on the stem of the valve 21, with the result that assuchvalve is screwed downwardly and the air consequently admitted to thetop of the reservoir valve 24 is automatically moved from its normalvertical position shown in Fig. 4 to a horizontal position,

closing the outlet of the discharge pipe 3 so that there will be nopossibility of any discharge of the contents of the reservoir back intothe discharge pipe 3 or of any backing up of such contents therein.

By preference the valve 24 operated in connection and in unison withanother valve 31 which is pivoted at the outer end o'l the iinaldischarge pipe 12, such valve being connected with the bell crank 2G bymeans of the link or rod 32, with the result that as the valve 24 ismoved to closed position the valve 31 is simultaneously moved to openposition.

Although I have herein shown only one water closet connected with thestorage tank it will be understood that all oi the water closets of thesame car may be connected therewith.
